Ulysses 2

Overview of Ulysses 2

Ulysses 2 is a submarine telecommunications cable system owned by Verizon. Commissioned in 1997, its primary purpose is to provide connectivity between the Netherlands and the United Kingdom. As a legacy system, it has been operational for over two decades, serving as a critical link in international data transmission between these two countries.

Geography and Landing Points

The Ulysses 2 cable spans the North Sea, connecting two landing points:

• Ijmuiden, Netherlands
• Lowestoft, United Kingdom

This direct route facilitates communication and data exchange between Western Europe and the British Isles, bypassing more congested terrestrial networks.

Architecture and Specifications

Ulysses 2 was ready for service in 1997, but detailed technical specifications such as its total length, fiber pair count, and capacity have not been publicly disclosed. Similarly, information about the supplier responsible for its construction remains unavailable. As a legacy system, it likely operates at lower capacities compared to modern cables, but its exact throughput is unknown.

Importance in Regional Connectivity

Ulysses 2 plays a significant role in enhancing connectivity between the Netherlands and the United Kingdom. It provides an alternative route for data traffic, reducing dependency on terrestrial networks and offering redundancy in case of disruptions. Its location across the North Sea makes it an important part of the regional cable topology, particularly for ensuring diverse routing options. However, as an older cable, its role may now be complemented or supplemented by newer systems such as Scylla, Zeus, and Iceni.

What Is Known and What Remains Undisclosed

Known details about Ulysses 2 include its operational status since 1997, ownership by Verizon, and its landing points in Ijmuiden and Lowestoft. However, many technical aspects remain publicly undisclosed, including its length, fiber pair count, capacity, and supplier. Additionally, information about maintenance history, upgrades, or specific operational challenges has not been made available.

Why Ulysses 2 Is Relevant for GeoCables Monitoring

From a risk-topology perspective, monitoring Ulysses 2 is essential due to its age and strategic location. Key areas for observation include:

• BGP paths: Tracking routing changes to detect any shifts in dependency on Ulysses 2.
• Latency: Monitoring latency metrics to identify potential degradation in performance.
• Marine activity: Observing vessel movements above the cable route to mitigate risks of accidental damage.
• Correlations: Analyzing traffic patterns to identify any impact from outages or maintenance activities on Ulysses 2.

Given the cable's age, proactive monitoring is crucial to anticipate and address potential vulnerabilities.

Conclusion

Ulysses 2 serves as an important legacy system connecting the Netherlands and the United Kingdom. While its technical specifications remain largely undisclosed, its role in providing redundancy and diverse routing options across the North Sea underscores its significance in the region's connectivity landscape. For GeoCables, monitoring this cable offers valuable insights into the stability and resilience of international communications infrastructure.
